The Gujarati alphabet, by mouth position
Gujarati script (ગુજરાતી લિપિ) is a sister of Devanagari. It drops the horizontal top-line but keeps the same phonetic logic: consonants are grouped by where in your mouth they're made. Learn the map once, and pronunciation of new letters comes for free.
Five zones, back to front
Within each zone you get four variants: soft, soft-aspirated, voiced, voiced-aspirated. Same tongue position, different puff of air and vocal cords.
One letter Devanagari doesn't have
Gujarati keeps ળ (retroflex L), heard in words like કાળું (kaaLu, "black"). Curl your tongue back the same way you do for ટ, then say an L. That single letter marks a lot of Gujarati vocabulary.
How it differs from Hindi
The scripts share ancestry, so if you can read Devanagari most of Gujarati falls into place within an hour. Where they truly split is grammar: three genders (including neuter), ને for objects, એ for ergative subjects. The app teaches those side by side.
